JOHN R. DEISI-IER, OF POTTSVILLE, PENNSYLVANIA.

CAR-COUPLING.

Specification of Letters Patent.

Patented Nov. 18, 1913.

Application filed July 15, 1909. Serial No. 507,788.

To all whom t may concern Be it known that l, JOHN R. Dni'snnn, acitizen of the United States of America, residing at Pottsville, in thecounty of Schuylkill and State of Pennsylvania, have invented new anduseful Improvements in Car- Couplers, of which the following is aspecification.

The invention relates to an improvement in car couplers, and isparticularly directed to a construction which may be set to permit anautomatic coupling, and which after such automatic coupling will lockagainst uncoupling.

The main object of the present invention is the provision of a couplerin which the coupling pin is adapted to be set in a single movement ofthe cutting lever to arrange the parts of the coupler for the automaticcoupling operation, the movement of the lever, as a result of the pinconstruction, locking the pin in set position against movement otherthan that induced in the coupling operation.

A further object of the invention is the provision of a coupling pin soconstructed that in normal position it will lock the movable jaw andknuckle in coupling position, and when in set or stopped position willrelease said parts to permit the coupling operation, the initialmovement of the jaw in the coupling operation releasing the lock of thestop pin and in turn supporting said pin against movement to couplingposition until the jaw has returned to coupling position.

The invention will be described in the following specification,reference being had particularly to the accompanying drawings, in whichFigure l is a plan of the improved coupler. Fig. 2 is a longitudinalsection of the same on line Q of Fig. 1, the coupling pin being shown inset position in dotted outline. Fig. 3 is a horizontal section throughthe coupler, the jaw and knuckle being shown in open relation in dottedoutline.

Referring particularly to the accompanying drawings, wherein is shownthe preferred details of construction, my improved coupler comprises ahead l, which, aside from the details to be hereinafter noted, is ofusual construction. Pivotally mounted at the usual point in the head isthe knuckle 2, the pivot pin 3 of which passes through the knuckleextension 1l and through both upper and lower plates of the head. rlheinner end of the extension l beyond the pivot 3 is laterally enlarged,as at 5, for a purpose which will presently appear.

Secured to the head in an appropriately opposing position relative tothe knuckle is the jaw (3, this jaw in the preferred construction beingpivotally mounted on a pin 7 extending through both plates of the headand through the jaw extension 8, it being understood that both theknuckle and jaw extensions are of such height as to fit in a mechanicalmanner between the plates of the head without permitting undue play ofsaid parts.

Projecting inwardly from the jaw extension is a section 9, which willhereinafter be termed, the locking plate. The plate is of materiallyless thickness than the extension S, and has its lower surfacecoincident with the lower surface of the extension. The inner edge ofthe plate adjacent the relatively forward edge is formed with a lip l0coextensive in height with the thickness of the plate and having itsremote or free end extending forwardly with relation to the plate. Theouter or remote edge of the lip 10 is designed to bear snugly againstthe proximate surface of the inner or rear end of the knuckle extensionl when the parts are in coupled position.

The locking plate 9 at a point approximately in alinement with thelongitudinal central line of the draw bar is formed with an aperture oropening l1 extending therethrough to receive the coupling pin to belater described. A slotted extension l2 is also formed in the plate incommunication with the opening l1, said slot extending rearwardly and ona line concentric with the pivot pin 7 of the jaw. The upper' and lowerplates of the head are formed with openings 13 and 14: respectively bothcorresponding in size to the opening ll in the plate and being inalinement therewith when the jaw G is 'in coupling position. The opening14: in the lower plate of the head is preferably formed in its forwardportion with a transverse abutment l5, serving as a ledge or stop tolimit the downward movement of the coupling pin proper, as willpresently appear, so that the opening lll is in its upper portion of thefull diameter of the coupling pin and in its lower portion partlyclosed, as clearly shown in Fig. 2.
